NASA Social Briefing on Planet-Hunting Mission Launch

NASA and industry leaders speak to NASA Social participants about the agency's Transiting Exoplanet Survey Satellite (TESS) in the Press Site auditorium at Kennedy Space Center in Florida. Speaking to the group is Tom Barclay, TESS scientist, NASA’s Goddard Space Flight Center. TESS is the next step in the search for planets outside of our solar system. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits.
